TESTING SEPARATE REED STEMS

Connect the pin electrode 2-E to the external connector on the top of the meter.

Prepare a representative sample by collecting 5 thick, slow drying reeds from
various parts of the bundle.

Insert the electrode into each reed stem

Press the read button (#1) and take a reading.

The average outcome of the stems will approximately 3-5% higher if compared with
the pen test
NOTES

Repeat the steps above if considerable variations are found in the meter readings
TESTING ROOFING SHEETS

Connect the pin electrode 2-E to the external connector on the top of the meter.

Insert the pins approx 5 mm into the sheet

Press the read button #1 and take a reading.

Make several tests on the roofing sheets
NOTES

The readings are not actual percentages but should be judged as reference.
FACTORS AFFECTING YOUR READINGS
Because of the many variables that affect the electrical meter readings, the indicated
moisture content should not be used as an absolute quantitative measurement. Meter
readings are very useful guidelines for safe use of reed.
Meter readings become more significant when they are considered in the light of the density
of the stacks, anticipated handling and storage, and prevailing climate conditions.
RANGE OF MOISTURE CONTENT
The F-2000 is designed to test moisture in reed over a range of 6%-40%. Readings over
30% should be used only as a qualitative indication of high moisture content. Delmhorst
moisture meters use the relationship existing between electrical conductivity and moisture
content in reed. As moisture content increases, so does the conductivity.
Tests on reed at high moisture content, over 25%, are less accurate. This is mostly due to
the variability in moisture distribution. The reduced level of accuracy in the high range does
not significantly affect the usefulness of the meter, as a few high readings indicate that
some action be taken to dry the reed to avoid spoilage or even self-combustion.
